Question

На тело объемом 1 м3,погруженное в жидкость,действует выталкивающая сила,равная 8кН.Чему равна плотность жидкости?

Answer 1

Fa=ρgV
ρ=Fa/(gV)=8000/10=800(кг/м³)

Answer 2

Calculation of Density of the Liquid

To find the density of the liquid, we can use the formula:

Density = Force / Volume

Given that the volume of the body is 1 m^3 and the force acting on it is 8 kN (kilonewtons), we can substitute these values into the formula to calculate the density.

Density = 8 kN / 1 m^3

To proceed with the calculation, we need to convert the force from kilonewtons to newtons, as the SI unit for force is newtons.

1 kilonewton (kN) = 1000 newtons (N)

Therefore, the force can be expressed as:

Density = 8000 N / 1 m^3

Now, we can calculate the density:

Density = 8000 N/m^3

So, the density of the liquid is 8000 N/m^3.

Please note that the specific liquid in question is not provided in the question, so we cannot determine the exact nature of the liquid.
